42 Chapter 4 WebMail
Users log in to WebMail with the name and password they use for logging in to regular
mail service. WebMail does not provide its own authentication. For more information
on mail service users, see the mail service administration guide.
When users log in to WebMail, their passwords are sent over the Internet in clear text
(not encrypted) unless the website is configured to use SSL. For instructions on
configuring SSL, see “Enabling SSL on page 35.
WebMail users can consult the user manual for SquirrelMail at www.squirrelmail.org/
wiki/UserManual.
WebMail and Your Mail Server
WebMail relies on your mail server to provide the actual mail service. WebMail merely
provides access to the mail service through a web browser. WebMail cannot provide
mail service independent of a mail server.
WebMail uses the mail service of your Mac OS X Server by default. You can designate a
different mail server if you are comfortable using the Terminal application and UNIX
command-line tools. For instructions, see “Configuring WebMail” on page 43.
WebMail Protocols
WebMail uses standard email protocols and requires your mail server to support them.
These protocols are:
Internet Message Access Protocol (IMAP) for retrieving incoming mail
Simple Mail Transfer Protocol (SMTP) for exchanging mail with other mail servers
(sending outgoing mail and receiving incoming mail)
WebMail does not support retrieving incoming mail via Post Office Protocol (POP). Even
if your mail server supports POP, WebMail does not.
Enabling WebMail
You can enable WebMail for the website (or sites) hosted by your web server. Changes
take effect when you restart web service.
To enable WebMail for a site:
1 Make sure your mail service is started and configured to provide IMAP and SMTP
service.
2 Make sure IMAP mail service is enabled in the user accounts of the users you want to
have WebMail access.
For details on mail settings in user accounts, see the user management guide.
3 In Server Admin, click Web in the list for the server you want.
4 Click Settings in the button bar.
